To further enhance the autoleveling technology of drawing frame, a new type of dual open-loop control system was issued based on the analysis of the quality of the current autoleveling control system of drawing frame. This paper presented a mathematical model of the new control system, analyzed its mathematical theory, and elucidated the theoretical basis of dual open-loop autoleveling control system.

为进一步提高并条机自调匀整技术，在分析纺织并条机自调匀整控制系统优劣的基础上，提出一种新的双开环控制系统，给出了新型控制系统的数学模型，详细分析了其数学原理，阐述了双开环自调匀整控制系统的理论基础。

Apparently, the evolution have generated the situation of the separation of monosyllabic form and disyllabic form, and thus generated the form system of direction words. The totally different paralleling dual system is the basis of the later evolution. The monosyllabic and disyllabic direction words has gradually come into the weakened meaning or morpheme,while disyllabic direction words has more substantive nature,with more freedom in the sentences.

可见，语义的发展变化最终导致了汉语方位词形式系统单双音节两分的局面，这两种形式方位词的不同语义特点也是后来发展演变的基础，单音节方位词逐渐走向虚词性或词法平面，而双音节方位词则具有更多的实词性，更为自由地出现在句子中。
